Definition of Main and Helping Verbs
Verbs are the backbone of any sentence, expressing actions, occurrences, or states of being. Within the realm of verbs, understanding the distinction between main verbs and helping verbs is essential for constructing grammatically correct and nuanced sentences.
Main Verbs
A main verb, also known as a lexical verb, is the principal verb in a clause or sentence. It carries the primary meaning and indicates the action, state, or occurrence being described. Main verbs can stand alone in a sentence or be accompanied by helping verbs.
For example, in the sentence “She sings beautifully,” the verb “sings” is the main verb. It expresses the action being performed by the subject “she.” Similarly, in “They are students,” the verb “are” is the main verb, indicating the state of being of the subject “they.”
Helping Verbs
A helping verb, also called an auxiliary verb, assists the main verb in expressing tense, mood, or voice. Helping verbs precede the main verb in a sentence and provide additional information about the action or state being described. Common helping verbs include forms of “be,” “do,” and “have,” as well as modal verbs like “can,” “could,” “may,” “might,” “must,” “shall,” “should,” “will,” and “would.”
For example, in the sentence “I am studying,” the verb “am” is the helping verb, and “studying” is the main verb. The helping verb “am” indicates the present continuous tense. In “He should go,” the verb “should” is the helping verb, expressing obligation or advice, and “go” is the main verb.
Structural Breakdown
The structure of sentences containing main and helping verbs typically follows a specific pattern. The subject is usually followed by one or more helping verbs, and then by the main verb. The helping verbs modify the meaning of the main verb, providing information about time, possibility, necessity, or other aspects of the action or state.
The general structure can be represented as: Subject + (Helping Verb(s)) + Main Verb + (Object/Complement)
Here are a few examples to illustrate this structure:
- She is reading a book. (Subject + Helping Verb + Main Verb + Object)
- They have finished their work. (Subject + Helping Verb + Main Verb + Object)
- He should study harder. (Subject + Helping Verb + Main Verb + Adverb)
In sentences with multiple helping verbs, the order is usually determined by the specific meaning being conveyed. For example, in the sentence “She will be going to the party,” “will” and “be” are both helping verbs, with “will” indicating future tense and “be” forming the continuous aspect.
Types of Helping Verbs
Helping verbs can be broadly classified into two main categories: primary helping verbs and modal helping verbs. Each type serves a distinct purpose in modifying the meaning of the main verb.
Primary Helping Verbs (be, do, have)
The primary helping verbs are forms of “be,” “do,” and “have.” These verbs are used to form different tenses, voices, and aspects of the main verb.
- Be: Used to form continuous tenses (e.g., “is running,” “was sleeping”) and the passive voice (e.g., “is written,” “was built”).
- Do: Used to form questions and negative statements in the simple present and simple past tenses (e.g., “Do you like it?” “I did not go.”). It can also be used for emphasis (e.g., “I do want to go!”).
- Have: Used to form perfect tenses (e.g., “has eaten,” “had finished”).
Modal Helping Verbs (can, could, may, might, must, shall, should, will, would)
Modal helping verbs express possibility, necessity, permission, obligation, or ability. They always precede the main verb and do not change form based on the subject.
- Can: Expresses ability or possibility (e.g., “I can swim,” “It can rain tomorrow”).
- Could: Expresses past ability, polite requests, or possibility (e.g., “I could swim when I was younger,” “Could you help me?” “It could rain tomorrow”).
- May: Expresses permission or possibility (e.g., “You may leave,” “It may rain tomorrow”).
- Might: Expresses possibility (e.g., “It might rain tomorrow”).
- Must: Expresses obligation or necessity (e.g., “You must study,” “We must leave now”).
- Shall: Expresses future intention (often used in formal contexts, e.g., “We shall overcome”).
- Should: Expresses advice or obligation (e.g., “You should study,” “We should leave now”).
- Will: Expresses future intention or prediction (e.g., “I will go,” “It will rain tomorrow”).
- Would: Expresses conditional statements, polite requests, or past habits (e.g., “I would go if I had time,” “Would you like some tea?” “He would often visit”).

Usage Rules
To use main and helping verbs correctly, it’s essential to follow certain grammatical rules. These rules govern subject-verb agreement, tense consistency, and the proper use of modal verbs.
Subject-Verb Agreement
Subject-verb agreement requires that the verb agrees in number (singular or plural) with its subject. This is particularly important in the present tense. For example:
- Singular Subject: He walks to school.
- Plural Subject: They walk to school.
When using helping verbs, the main verb usually remains in its base form, but the helping verb must still agree with the subject. For example:
- Singular Subject: He is walking to school.
- Plural Subject: They are walking to school.
Tense Consistency
Tense consistency requires that the verbs in a sentence or paragraph maintain a consistent tense. This helps to avoid confusion and ensure clarity. For example:
- Incorrect: I went to the store, and I will buy some milk.
- Correct: I went to the store, and I bought some milk.
- Correct: I will go to the store, and I will buy some milk.
When using helping verbs, ensure that the helping verb and main verb work together to maintain the correct tense. For example:
- Incorrect: She was going to the store, but she did not bought anything.
- Correct: She was going to the store, but she did not buy anything.
Modal Verb Rules
Modal verbs have specific rules that govern their usage:
- Modal verbs are always followed by the base form of the main verb (e.g., “can go,” “should study”).
- Modal verbs do not change form based on the subject (e.g., “I can go,” “He can go”).
- Modal verbs cannot be used together (e.g., “I will can go” is incorrect; use “I will be able to go”).
- To express past forms of modal verbs, use “have” + past participle (e.g., “should have gone,” “must have studied”).
Common Mistakes
Several common mistakes can occur when using main and helping verbs. Being aware of these errors can help you avoid them.
| Incorrect | Correct | Explanation |
|---|---|---|
| I can to swim. | I can swim. | Modal verbs are followed by the base form of the verb, without “to.” |
| She does liking coffee. | She likes coffee. | In simple present affirmative sentences, use the base form of the verb with -s/-es for third-person singular. |
| They are finish their work. | They have finished their work. | “Are finish” is grammatically incorrect. Use “have finished” for the present perfect tense. |
| He should went to the doctor. | He should have gone to the doctor. | To express past obligation or advice with “should,” use “should have” + past participle. |
| I will can go. | I will be able to go. | Modal verbs cannot be used together. Use an equivalent expression like “be able to.” |
| She is sings beautifully. | She is singing beautifully. | To form the present continuous tense, use “is” + the -ing form of the verb. |
| They has finished their homework. | They have finished their homework. | The helping verb “have” must agree with the plural subject “they.” |
| He don’t like it. | He doesn’t like it. | Use “doesn’t” for the third-person singular in negative sentences. |
| I am agree with you. | I agree with you. | “Agree” is a stative verb and does not typically use the continuous form unless emphasizing a process. |
| She must to study hard. | She must study hard. | Modal verbs are followed by the base form of the verb, without “to.” |

FAQ
Here are some frequently asked questions about main and helping verbs.

main verb by providing additional information about tense, mood, or voice.
- Can a verb be both a main verb and a helping verb?
Yes, some verbs, like “be,” “do,” and “have,” can function as both main verbs and helping verbs, depending on the context. When they are the only verb in the sentence, they are the main verb. When they accompany another verb, they are helping verbs.
- How do I identify helping verbs in a sentence?
Helping verbs usually precede the main verb. Look for forms of “be,” “do,” and “have,” as well as modal verbs like “can,” “could,” “may,” “might,” “must,” “shall,” “should,” “will,” and “would.”
